Answer: The moles of melatonin are 0.000043

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}

Given mass of melatonin = 0.01 g

Molar mass of melatonin (C_{13}H_{16}N_2O_2) = 232.28 g/mol

\text{Number of moles of melatonin}=\frac{0.01 g}{232.28g/mol}=0.000043mol

Thus the moles of melatonin in 0.01 g are 0.000043
